TILE MAKING ATTACHMENT FOR BRICK-MACHINES.

SPECIFICATION forming part of Letters Patent No. 315,016, dated April '7, 1885.

Application filed September 12, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN B. FOSTER, asubject of the Queen of Great Britain, residing at Zurich, in the county of Huron and Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Tile-Making Attachments for Briclz-lVIachines; and I do hereby declare that the following is a full, clear, and exact description of the same, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to the addition of a tile-making attachment to a brick-machine; and it consists of devices suitable for forming and expelling the tiles, as hereinafter specified.

In the accompanying drawings, Figure l is a front elevation of the machine. Fig. 2 is a side elevation. Fig. 3 is a view of tile-forming attachment detached. Fig. 4. shows the forming-box to receive the clay.

The machine to which my attachmentis particularly intended to be applied is known as The Martin Brick-Machine, but the invention may be applied to any other brick-machine of suitable construction. In the Martin machine, as shown in Figs. 1 and 2, steam or horse power is applied on top, giving r0- tary motion to the perpendicular central shaft, A. Curved arms at the bottom of this shaft inside the machine push forward the clay into the forming-box; but the interior construction is notshown, as it forms no part of myinvention.

B is the crown-wheel attached to top of shaft A, and the revolution of this wheel operates pinions O D, with which it engages.

E is a crank on shaft of pinion O, and to this crank is pivoted the pitman-rod F, which is pivoted at the other end to bar G, tothe bottom of which is attached the compressing plate or block H in front of machine, and the revolution of crown-wheelB causes this block to alternately rise and fall, compressing the clay into shape as the latter is driven for ward.

All these parts are portions of the original machine, to which no claim is herein made.

The other pinion, D, has asiinila-r crank, I, keyed to its shaft, to which the rod J is pivoted, the other end of which rod is pivoted to one end of another crank, K. The opposite end of this crank is attached to shaft L, Fig. 3, lying under the machine and journaled thereto. On this shaft are centered a pair of disks, M, about one-half of each of which is toothed or cogged, so as to mesh into the toothed racks N, secured by top plate, 0, but moving freely underneath said plate. Tothe forward end of these racks is attached ablock. P, and the revolution of crank K by means of rod J, operated by upper crank, 1, causes the cogged disks M, in engaging with racks N, to drive the block P forward, and so to push the clay out through the tile-forming molds in front at Q as soon as theblock or plate H begins to rise after it has pressed down the clayinto forming-box B. This box is shown separately in Fig. 4, and has a longitudinal slit or opening, a, in top, into which the clay is pressed by the block or plate H, and passing out in front at Q, in the shape of tiles.

No claim is made to the general construction of the machine above described; but

JOHN B. FOSTER.
